I'm not subscribed to any of her pages so I can't really comment on the specifics. I've just seen several people (who claim to be subscribers of hers) say that she uses watermarks to identify those who leak her content. I remember seeing a screenshot that showed Maple threatening anyone who leaks her content with legal action.
I don't necessarily have a problem with how she sells her content. Atleast she is selling what she is advertising unlike most youtubers who call sucking a dildo blowjob or other misleading nonsense plastered all over their feed. What you see is what you get from her. Although, I preferred her looks before all that plastic went into her face.
Sorry if it's a dumb question, not really familiar with OF, Im more of a ManyVids kinda guy
I just assumed she watermarked it all since her stuff never gets shared anymore (not even the bare minimum shit).
